Abstract

Methods and apparatuses for improved uplink establishment in wireless networks are presented. For example, a method of mobile communication at a user equipment is presented that may include receiving, at a user equipment (UE) and from a network entity, configuration information associated with an enhanced uplink in CELL_FACH state protocol, wherein the UE is configured to transmit uplink transmissions according to the enhanced uplink in CELL_FACH state protocol. Additionally, the example method may include determining that the configuration information includes invalid configuration information. Moreover, the example method may include performing at least one remedial action to ensure that the UE is able to transmit the uplink transmissions based on determining that the configuration information includes invalid configuration information.
